Flash Builder 4.5 Debugger Problem

Question

Hey Everyone,
I spent the better half of the last hour searching for a remedy to my situation but have not found one. I have a problem where in Flash Builder 4.5 I keep losing my debugger version of Flash Player. I download the version here http://www.adobe.com/support/flashplayer/downloads.html#fp10 and it works again. However, seemingly random it will do it again a couple of days later. So I'm trying to figure out what is causing this or how I can fix it. It is quite annoying to go to jump into a project, debug it and then have to stop everything and download it again. Anyone know how to fix this?
I am running it on Mac OSX 10.6.7 (latest).
This is the message I receive when it breaks:
"Flash Builder cannot locate the required debugger version of Adobe Flash Player. You might need to install the debugger version of the Flash Player or reinstall Flash Builder.  Do you want to try to debug with the current version?"

My two cents on this issue & how I resolved it.
I was getting a similar message which referenced a location in C:\Windows\System32\Macromed\Flash, and was looking for this version of the Flash Player: Flash64_10_3_162.ocx
What I tried that did NOT help:
Re-associating the SWF file type to open with a Flash Player debugger version downloaded from Adobe's site.
These three steps resolved the issue for me:
I had installed the 64-bit version of the Flash Player a few months ago, so I uninstalled that since it cannot be used by Flash Builder as a debugger. Back in FB 4.5.1, I got another message saying Flash was not installed at all.
I used Adobe's Flash uninstaller tool and then,
re-installed the latest debuggers for IE & Firefox.
I can now debug in IE or FF without any issues. FB finds the debug version of the Flash Player.
From what I saw when researching this, there seem to be many causes for this issue so I'll give Adobe some slack here. I will point out that the post from Adobe employee Anirudh Sasikumar, above, was not helpful in my case and was in fact misleading and not specific enough as to the location of the file he referenced. I searched for that file and found dozens of them on my machine, none in any location he mentioned. I wish he would have taken a little more time to give a complete path to this file. Maybe he did, but I could not find that path, or folders, on my machine. I work in a tightly-controlled network environment so perhaps these folders are ones I cannot see due to permissions issues, but it would've saved me time to get a complete path to start with.
For complete and full disclosure, here is my set-up; hopefully this will help others with a similar setup who are experiencing this nagging issue:
Windows 7 Enterprise 64-bit, Service Pack 1
Flash Builder 4.5.1.313231
Eclipse 3.6.1r361_v20100909xxxxxxx
Flash Debugger version (IE & FF): 10.3 r183
